Hi Folks,

I have just finished building my new Lian-Li V351R but when I boot it up for the first time I could hear very loud fan noise coming from my OcUK Value GeForce GT 240 graphic card. I think it was spinning at top speed.

This one: http://www.overclockers.co.uk/showproduct.php?prodid=GX-129-OK

I know the noise came from graphic card fan because I disconnected the rest of the fans (40mm x 2, 80mm & Akasa Exhaust Blower) to check for the culprit.

Please note that I have not installed/set anything to the PC yet. i.e. I just simply switched it on to check the fans push/pull capability and not setting the BIOS or HDD to AHCI yet, so no drivers etc.

This is my spec:

1) Lian-Li V351R.
2) Gigabyte GA-P55M-UD2 (mATX)
3) Windows 7 Home Premium 64bits (not install yet)
4) Corsair H50 Water cooling.

Question:

1) Is it normal that the fan on a video/graphic card will spin at the maximum if I have not installed the driver or set up my PC yet?

2) Will the fan calm down after I installed everything? bios set up, HDD set up, drivers etc.

Cheers

Yes, sometimes if the driver is not installed then the fan can go to full speed. In fact my graphics card even does this when even turning on the computer until the driver is loaded.

So install everything including the latest drivers and the fan should quieten down as the driver will control the fan speed temperature dependent.

Fan speed control is done by the drivers so yes it would spin at full chat without them. The drivers regulate the fan speed according to GPU temperature.

Thanks for your advice folks.

I can have the peace of mind now and proceed to next step.

If you do find the fan speed is still too loud after installing the driver, you can then download program such as MSI Afterburner and set your own fan profile for setting the auto-control for temp vs fan speed.

I use the MSI Afterburner to set my 9800GTX+ fanspeed as...fanspeed %=temp (i.e. 40% at 40C, 50% at 50C).

Thank you.

That's a piece of very good info for me as I don't know I could do that.

Cheers
